Works great to replace the defective original rheostats in my Cessna 150L. Something worth noting -- the slightest bit of panel modification was needed to make them fit in the original space (about 20 seconds with a dremel and done).

Another MAXDIM product for me. I used the DUODIM for dash lights and overhead but do not like dash lights and EI gauges controlled by same line. So I purchased this singe dimmer and it is controlling ALL my EI gauges. This way I have more control over lighting intensities, dash vs EI.
